Selective Withdrawal for Reducing Turbid Water in a Reservoir
This paper deals with improvemental operations of the selective withdrawal facilities as one of the comprehensive technics for shortening the turbid water stay after floods flown into...

Three-Dimensional Modeling of Tides and Wind-Waves
A third-generation coupled discrete numerical wave prediction model is dynamically linked to a three-dimensional hydrodynamic model. The effects of water level, currents, and bottom friction...

Thermal Shielding in Continuous Span Composite Slabs
The increasing popularity in Europe of composite slabs with cold-formed steel decking has underscored the need to improve calculation rules for the fire resistance. Existing rules have...

An Evaluation of Fiberglass Pipe Made by Three Different Manufacturing Processes for use in Water Transmission Projects
Fiberglass pipe is made primarily using continuous filament wound process, discontinuous helical filament wound process, and centrifugal cast process. Some 40 countries around the world...

The Design and Development of A Road/Rail Power Unit
The road/rail power unit was designed and developed by Saskatchewan Highways and Transportation to provide low cost motive power on low-density disconnected rail lines. The power unit...

How SHRP Reliably Predicts Pavement Performance
One of the important results of the SHRP Asphalt Research Program was to develop a comprehensive pavement performance model that reliably predicts rutting, fatigue cracking and thermal...

SHRP Deformation Test?Asphalt Mix Tests and Analysis Systems
From analyses of existing information on the permanent-deformation characteristics of asphalt/binder-aggregate mixes, as well as the development of permanent deformation in pavement structures,...

Detecting Leaks in Geomembranes
A field-tested leak-location survey, now commercially-available, can provide construction quality assurance or solve a leakage problem in lined landfills, impoundments or tanks. A liner...

Properties of Bottom Ash-Based Composite
High-calcium bottom ash, a by-product of the electric power industry, was evaluated for feasibility of use as a fine aggregate in structural grade concrete. Both fresh and hardened properties...

Characterization of Man-Made Vitreous Fibers by Image Analysis
This paper deals with the characterization of man-made vitreous fibers (MMVF), seen as an application of the techniques of image analysis and mathematical morphology. We present the whole...

Radiographic Visualization in Experimental Soil Mechanics
A summary of the principles of such methods is presented, i.e. stereophotogrammetry, infrared thermography and radiography and their respective ranges of applicability are discussed. Then,...

Mechanistic Design Models of Loading and Curling in Concrete Pavements
Determination of the critical bending stress at the edge of a concrete pavement due to individual and combination effects of wheel loading and thermal curling is very crucial to any mechanistic...

Mathematical Modeling of Airport Pavements
Theories for analyzing rigid pavements are presented. The emphasis is on the choice of the proper models for the pavement and for the subgrade, and on the correct mathematical formulation...

Durability of Asphalt Mixture
Five asphalts were used in a laboratory testing program to establish a relationship between mixture properties and the binder properties. These five asphalts were used to make Florida...

Chicago-O'Hare International Airport Transit System (ATS)
This paper describes the development of the O'Hare Airport Transit System, as well as, the individual subsystem elements which make up the entire system. In addition, the paper also describes...

Denver International Airport AGTS?A Progress Report
Denver International Airport (DIA), the first major airport to be built in the United States in nearly 20 years, is under construction approximately 25 miles (40 km) northeast of downtown...

Automatic Power Factor Correction Equipment?The TrAAm People Mover System
The introduction of the American Airlines' TrAAm project brought numerous modifications to support the addition of guideway, stations and the operation of three-car trains to the existing...

Regeneration?Potentially Powerful Stuff
Virtually all Automated People Movers (APMs) use electrical power for propulsion. Many designs also use electrical braking to augment any mechanical braking devices for decelerating trains....

Speedy Backfilling for Old Mines
In November 1992, the U.S. Bureau of Mines, in cooperation with the Office of Surface Mining (OSM), used two recently-developed pneumatic backfilling devices to completely fill an abandoned...

Lost & Found: Comeback at the IDB
With the lost decade of the 1980s behind it, Latin America has emerged from its debt crisis as a project powerhouse. Fueling many of those projects is the Inter-American Development Bank...
